Image embossing & G-Code output example

[dcarr]

With the recent talk on this forum regarding converting digital images to G-Code, I decided to put together a tutorial which shows how it is done in VS3D.

In case anyone is interested, the process can be seen at:

Thanks.

Paul, how about a VS3D forum?

Hi, I tried the demo and the tutorial.

The tutorial with the blonde girl and white dress worked very well. The photo carving doesn't seem to work near as well with a Caucasian that has dark clothing, brown hair, and a light background.

Am I doing something wrong? or is the tutorial photo carefully chosen to minimize problems?

Really though, your program seems to bring in JPEGS much better than any other program I have tried. It is a very impressive piece of software.

Good luck

Trent,

Thanks,

Yes, there is no "magic bullet" when dealing with images.
The basic techniques is to scale image brightness into surface height.
That image of the girl is one that happens to work well.

Typically, though, the image brightness does not always correlate well with the desired surface heights. For example, a person's eyebrows are often darker than the surrounding skin. When converting to surface height, the eyebrows will be sunken in.

That is where the other sculpting tools in VS3D come into play. By using the region tools and/or hammer tools, you can pull the eybrows up to the desired height. It does take a little practice and skill to do that well.

Another option is, of course, to use one of the available 3D optical scanners to scan a face and then import it into the program as a DXF or STL file. Then you can machine it.

ger21,

Yes, I would be very interested in having CNCZone host a VS3D forum. Let me know what I can do to assist in getting one set up.
